As E3 rolled on late yesterday, Valve released the very first footage of Portal 2, the upcoming sequel to its first-person action puzzle game. You can view the teaser clip here on the Steam website, but we've uploaded it to YouTube for your convenience:
This teaser doesn't reveal a whole lot about the game, except perhaps that GLaDOS is still alive (what a shocker) and that Portal 2 will take place in overgrown testing areas designed around the same principles as the first game's environments.
Another YouTube video, this time submitted by This Week In Tech, gives us a brief look at actual gameplay footage. That clip shows one especially interesting gameplay element: interactive liquid physics. Apparently, you'll be able to send liquid (or whatever that orange goop is) spewing through portals. Neat!
Portal 2 is scheduled to come out for the PC, Xbox 360, and PlayStation 3 next year. As Shacknews reports, Valve's Gabe Newell broke the news yesterday that the PS3 edition will feature Steamworks support. Newell commended Sony, calling its console "the most open platform of all the current generation consoles" and adding that Portal 2 for the PS3 will be "the best console version of the game."
